<para><command>badblocks</command> searches a device (usually a disk
partition) for bad blocks.</para>

<para><command>blkid</command> is a command line utility to locate and
print block device attributes.</para>

<para><command>chattr</command> changes the attributes of files on a
second extended (ext2) file system.</para>

<para><command>compile_et</command> is an error table compiler. It
converts a table of error-code names and messages into a C source file
suitable for use with the com_err library.</para>

<para><command>debugfs</command> is a file system debugger. It can be
used to examine and change the state of an ext2 file system.</para>

<para><command>dumpe2fs</command> prints the super block and blocks group
information for the file system present on a given device.</para>

<para><command>e2fsck</command> is used to check, and optionally repair,
second extended (ext2) file systems, and also ext3 file systems.</para>

<para><command>e2image</command> is used to save critical ext2 file system
data to a file.</para>

<para><command>e2label</command> will display or change the file system
label on the ext2 file system present on a given device.</para>

<para><command>findfs</command> finds a file system by label or UUID.</para>

<para><command>fsck</command> is used to check, and optionally repair,
file systems. By default it checks the file systems listed in
<filename>/etc/fstab</filename></para>

<para><command>logsave</command> saves the output of a command in a logfile.</para>

<para><command>lsattr</command> lists the attributes of files on a second
extended file system.</para>

file system on the given device.</para>

<para><command>mklost+found</command> is used to create a
<filename>lost+found</filename> directory on a second extended file system.
It pre-allocates disk blocks to this directory to lighten the task of e2fsck.</para>

ext2 file system.</para>

<para><command>tune2fs</command> is used adjust tunable file system
parameters on a second extended file system.</para>

identification and token extraction.</para>

<para><command>libcom_err</command> is the common error display routine.</para>
